DRIIIKING-CUP DEVICE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed July 12, 1910. Serial No. 571,647.

To all whom'z't may oohcem Be it known that we, JAMES H. MAnsrnRs andALBERT ABRAHAM, both citizens of the United States, residing,respectively, at Looking Glass an Roseburg, in the county of Douglas andS ate of Oregon, have invented certain new and useful Improvements inDrinking-Cup Devices, of-which the following is a specification.

Our invention relates to an improved drinking cup for use principally inpublic places and its objects are to provide a sanitary device having acup adapted to be destroyed after a single use and adapted to beremovably held within a supporting glass or cup which cannot itself beused for the purpose of drinking therefrom and. which renders necessarythe use of the removable cup, and to provide means on the removable cupto cover the upper edge of the supporting cup and thereby protect suchedge from contamination resulting from prior uses.

To these ends our invention is embodied in preferable form in the devicehereinafter described and illustrated in the accompanying drawings.

' In these drawings, Figure 1 is a side elevation of our improveddevice; Fig. 2, a vertical section therethrough; and Fig. 3, an invertedplan of the supporting member.

Referring to the drawings, 1 is a supporting cup or holder which may beof any suitable material such as metal or glass, it being shown in thedrawing as made of glass. This glass as shown and as preferably made, isof the same shape and size as any ordinary drinking glass. In the bottom2 thereof are provided holes or openings 3 for the purpose of preventingits use as a drinking glass; it being clear that if it were attempted toso use it, that the water poured therein would escape through theopenings. Within this glass is adapted to be placed a cup 4. This cup atits upper edge is provided with a protecting portion 5 which rests onand covers the upper edge of the glass 1, and is also provided with aprotecting wall 6 made in continuation of the portion 5 to furtherprotect the upper edge of the glass 1. These cups are freely removablefrom the glass 1 and aremade of a cheap material such as paper, whichmaterial is Weaker than the material of the holder 1. By reason of thesupport which the cup 4 receives from the glass 1, such cup ispreferably made of thin paper, so that after a single application ofwater thereto, it will collapse and be unfit for a second use. To theinterior of the cup 4 is preferably applied a thin coating of paraflinor similar substance to render such cup impervious to water and therebyprevent leakage therethrough into the outer cup member 1. These cups 4are intended to be destroyed after a single use and hence are made to befreely inserted into or removed from the holder or glass 1. They arealso made of a shape which allows them to telescope into each other andto be nested so, as to occupy small space.

At a public drinking fountain or elsewhere where our invention is putinto use, we preferably employ one or more of the holders 1 and a largenumber of the cups 4 which are placed in a suitable receptacle in stacksand when a person desires to drink from the fountain he removes one ofthe cups 4 and places it into the holder 1 and then uses the device asan ordinary cup or glass. After drinking therefrom, he re moves the cup4 and destroysor discards the same. Areceptacle is preferably employedto receive the discarded cups.

It is clear that any means to prevent the retention of a liquid in theholder 1 may be employed and that other changes may'be made withoutdeparting from the principle and scope of our invention;

Having thus described our what we claim is 1. In a drinking device, incombination with an outer, rigid, permanent vessel perforated to preventthe retention of liquid therein, of an inner liquid holding cup capableof a single use only and conformed to the shape of the outer vessel andsup.- ported thereby and made of thin, fragile material pervious towater and inoperable to permit a second use of the cup as a drinkingmeans, substantially as described,

2. In a drinking device, the combination with a rigid, permanent holder,provided with means to prevent its use as a drinking vessel, of animperforate liquid receiving invention,

lining cup member made of thinfragile ma:

inner surface of the wall of the outer vessel 5 with an outer, rigid,permanent, holder member provided With perforate means operable toprevent the retention of liquid therein, of an inner imperforate liquidreceiving cup of thln, fragile, flexible, ma-

10 terial requiring exterior support, said cup beingvadapted to fitWithin the holder memberand having at its edge an integral dependingprotecting and supporting flange depending from the cup outside of theholder, substantially as described.

In testimony whereof We have aflixed our signatures in presence of twoWitnesses.
